Good vendors will guide you through data management and set up smart pipelines. They’ll also align the GenAI solution with your current software development stack.
Ask what Generative AI tools and platforms they use. Do they fine-tune LLMs, or just wrap third-party APIs?
Look for teams skilled in custom generative AI, not just general AI services. This makes a significant difference when handling sensitive internal data or complex workflows.
Pro Tip: Ask how they train language models and what safeguards they have in place for accuracy, security, and bias control.
The right partner won’t just write code. They’ll help you create value with the right AI-powered solutions.
62% of AI‑driven value comes from core business functions, meaning that working with the right vendor on projects aligned to your key workflows drives the greatest ROI.
Choose wisely, your GenAI success depends on it.
